LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 349,013, dated September 14, 1886.

Application filed June 27, 1885.

To all whom it may concern.-

Be it known that we, AMOS B. TAYLOR, of vVollaston, in the county of Norfolk and State of Massachusetts, and J ACOB P.'TIRRELL,of Chelsea, in the county of Suffolkand State aforesaid, citizens of the United States, have invented certain Improvements in Loom shuttles, of which the following. is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view of a loom-shuttle having our improvements applied thereto. Fig. 2 is a central vertical section through one endof the same; Figs. 3and 4, horizontal sections on the line 00 w of Fig. 2. Fig. 5 is a transverse vertical section on the line y 3/ of Fig. 2. Fig. 6 is a side elevation of a portion of one end of the shuttle. Fig. 7 is a transverse vertical section on the line a a of Fig. 6. Fig. 8 is a longitudinal vertical section on the line b b of Fig. 7. Fig. 9 is a view of the tension-regulating swivel. Fig. 10 is a view of the metal eye-piece or bushing. Fig. 1.1 is

a plan of a portion of one end of the shuttle,

the metallic covering-plate being removed.

Our invention relates to loom-shuttles, and has for its object to provide a simple and effectivedevice, capable of easy adjustment, for regulating with great nicety the tension of the thread as it runs from the cop or bobbin to the eye or educt, and also to facilitate the operation of directing the thread-from the cop or bobbin to the eye.

To this end our invention consists in certain peculiar and novel features of construction and arrangement embracing a revoluble tensionregulating device, a slotted plate for guiding the thread to the tension-regulating device, a shuttle-body having a peculiar guide-slot for leading the thread to the shuttle-eye, and a peeuliarly-constructed eyepiece; and our invention also consists in certain details of construction, as hereinafter set forth and specifically claimed.

In the said drawings, A represents the shuttle-body, and B the pivoted spindle located, as usual, within the recess or chamber I), the shuttle-bodyand spindle being constructed in any well-known manner.

Serial No. 170,023. (No model.)

At the end of the shuttle-body B, in front of the point of the spindle, is formeda recess, 0, communicating with the chamber I), and within this recess 0 is placed a conical or cylindrical swivel or bell shaped thimble, D, which has continuous closed sides, and which is held in place by a screw, e, passing vertically through an aperture at its center into the body A, and forming a vertical pivot or center, around which the said thimble may be turned, a washer, f, of leather or other suitable material, being placed immediately under the head of the screw to produce sufficient friction to hold the swivel firmly, and yet allow it to be turned or adjusted around the screw e as a center, which may be accomplished by means of a key or wrench applied to holes h, or in any other suitable manner. Projecting u'p'from the enlarged base ll of this swivel is a pin or arm, 7:, between which and the outer surface of the swivel passes the thread Z, which also passes partially around the body'ofthe swivel on its way from the cop or bobbin to the eye or educt m in the side of the shuttlebody, and when the swivel is turned into the position seen in Fig. 3 the thread, after passing around it, will extend almost in a straight line to the eye at with the minimum amount of tension; but as the swivel is adjusted by turning it on its axis in the direction of the arrow the position of the pin with respect to the eye m will be varied, and the thread will be compelled to take a more or less sharp turn around the pin 7c on its way to the eye, as seen in Fig. 4;, thus causing it to be drawn with more or less friction against the pin is in accordance with the angle formed by the thread in passing around it, whereby the tension is increased or diminished, as desired. WVhen the pin is in the position seen in Figs. 3 and 11, its upper end lies in contact with a shoulder or projecting portion, 9, of the wall of the recess 0, as seen in Fig. 11,which thus serves as a stop for limiting the movement of the swivel in one direction, and thus preventing it from being moved out of its proper position. The thread is prevented from working upward by the tapering form of the swivel; but as a still further preventive we prefer to provide the swivel with an annular groove,

a, near the base, for the reception of the thread,which lies therein, and is thus kept in place on a level with the eye m.

To the upper surface of the end of the shuttle-bodyA is fitted a metal plate, G, of the form seen in Fig. 1, having a circular aperture, q,which lies over and is of slightly larger diameter than the upper end of the swivel 1), thus leaving an annular space between the two to allow of the thread being passed around the swivel, and leading into this aperture q is a diagonal slot, 1', extending out to and through the end of the plate, this slot also connnuni eating with a space or narrow passage, 8, formed between the edge of the plate G and the inner wall of the chamber Z), the said passage a communicating with an inclined slit or throat, i, in the side of the shuttle-body leading to the eye or eduet m.

Extending down from the under side of the tongue or portion a of the plate G to the bottom of the chamber 1) is a guide-pin, 1v, bent in the form shown in Figs. 2 and 5, which serves to keep the thread in line with the axis of the spindle as it is drawn off the point of the same, thereby avoidingliability of break age. Furthermore, the curvature or inclination of this pin counteracts any tendency of the thread to ride or work upward, and in connection with the tapering form of the swivel and the annular groove near the base thereof keeps the thread on a level with the eye m. The swivel is preferably provided with a notch or mark, 12, to indicate the position of the pin or arm hand the consequent angle at which the thread is being drawn thereover to the eye at, thus facilitating the operation of regulating the tension.

In the operation of threading the shuttle the thread is first caught under the point of the tongue 10 of the plate G, and thence passed through the slot 9' to the aperture q, and around the swivel, and between it and the pin it back to the slot 0', and again through the latter to the passage 8, through which it is passed to the slit t, and thenceinto the eye m, the thread being in this manner rapidly and easily directed from the cop or bobbin to the eye m, requiring no special care or attention on the part of the weaver. The tapering form of the swivel enables the thread to be easily caught around its upper edge as it is passed around it,and also causes the thread to assume its proper position near the base of the same as it is carried back through the slot 0' and slit t to the eye m.

The metal eye -picce or tube a, Fig. 10, which forms the bushing of the eye at, is pro vided with a slot, 1), the straight portion 12 of which lies immediately under and in line with the slit or throat t in the shuttle-body, so as to admit the thread. The outer end or portion, 13, of this slot 1) is inclined, as seen in Fig. 10, by which means the passage through which the thread finally enters the eye is re moved to one side out of line with the slit t,

as seen in Figs. 1 and 6, so that the overhanging upper edge, 15, of the groove 0 of the shuttle-body will prevent the thread from get ting back into the inclined portion 13 of the slot Z), while the portion 16 of the eye-piece extends under the lower end of the slit 1 and serves as a guard to prevent the passage oi the thread thereto. Consequently alter the thread has once been entered within the eye it cannot escape therefrom during the movements of the shuttle.

l. The combinatioinwith ashuttlebodyprovided with a thread eduet or eye, 01' a swiveled thread-guiding thimble, l), secured in a recess in the shuttle-body, having continuous closed sides diverging upwardly from the base, a tension pin or arm, If, and an annular groove formed around its base, whereby the thread is prevented from working upward, substantially as herein described.
